Abstract

In the quest of averting the drawbacks of alloys of titanium in advanced manufacturing, the laser metal deposition technique is used to fabricate suitable coatings with innovative microstructural evolution and unique surface properties in aggressive environment. The vital factor to be considered during direct laser metal deposition process is the simultaneous action of melting and fusion of the coating material to the base metal. The appropriate selection of laser processing parameter produced desirable result and properties. At scanning speed of 1.2Â m/min, Al-10Sn-5Si coating has an ultimate hardness of 463.57 HV whilst at the scanning speed of 1.0Â m/min the value has decreased to 398.36 HV (65.21 HV difference). Sample Al-10Sn-3Si also showed the same trend in increase hardness at 1.2Â m/min. While Al-10Sn-1Si did not follow the trend of other two coatings. The model was developed to obtain insights on the behaviour of laser melted pools subjected to various process parameters. Simulation with 3D model with different values of various significant processing parameters such as laser power, scanning speed and powder feed rate influences the geometry and dynamics of the melt pool, and cooling rates.
